are of a cross-section as shown best in Figlwindow frames and has for one of its princi.

' use ofputt-y or the like.

pal objects the provision of means for holdmg a wmdow pane in the 'frame without the One of the important objects of this invention is to provide a metal window frame into Ill which a glass pane can be readily inserted and positively retained; a frame which will not warp or swell in the presence of moisture or other deteriorating weather conditions, and which can be economically manufactured and marketed and conveniently installed.

One of the chief disadvantages of the ordinary window frame is the extreme care which must be takeniin cutting the .glass to fit the frame, and to accurately cut the glass to fit a warped window frame is at best a considerable task. If the pane is cut just a trifle too large, and a change in weather conditions occurs, the glass having very little or no'rooin to expand, is bound to crack.

Another important object of theinvention is the provision of means in a window frame,

. for allowing a free and untrammeled expansion or contraction of the glass to take place and yet firmly hold the same against rattling and vibrating, and also rendering the'same water and air tight.

Otherand further important objects ofthe invention will be apparent from the disclosures in the accompanying drawings and following s'pecilication. p

.The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully describedl- In the drawings: A

taken on the line 4-4 of Figure 1.

Figure 5 is an enlarged sectionaLview of a v modification of the upper rail of the invention.

As shown in the drawings: The reference numeral 10 indicates generally the usual glass window pane mounted'in "an improved window frame 12. Beth sides or' the said frame and also the bottom rail The three aforementioned portions of the frame 12 are constructed in the form of a hollow casing 1 4, closed at one side by an integral wall 16, and in the other side of which v is a slot 17 formed by two invs ardly extending edges 18 between'which the pane 10 is adapted to be held. A strip of resilient material 20, such as rubber or the like, is normally p0. sitioned between each portion 18 and the edge ofthe glass within the slot. A resilient clamp 22 U-shaped 'in cross section is positioned within the casing 14,- the edges' of which are adapted to bear upon the portions 18, thereby firmly clamping the said portions upon the edge of the pane. Elements 24 and 26 inv-tegral with the casing 1,4 extend outwardly therefrom at right-angles to the wall 15 and form a channel therewith. In this channel a filler 28, preferably of wood, is positioned.-

.An upper rail rail 30 ofthe frame 12 is constructed slightly different fromtheother three sides of theframe, as shown lbest in Figure 3, a slot 42 being provided at its top for the insertion or removal of the pane 10. Ihe remaining features of the rail 30 are the samel as the other three sides. Access is had to all the clamps 22 by means of openings 40 provided inthe sides, top and bottom of the frame 12 as shown best in Figures 1 and 2.

A modification of the upper rai in Figure 5. Each of the lateral Walls 32 and 34 of the rail is provided with a guide 36 at its upper end, into which a sectioned mem-- ber 38 is slidably positioned. The staff of ythe said member extends downwardly from the cross portion and is adapted to contact with the upper portion 4of the resilient clamp 22, thereby compressing the open edges of the same upon the inwardly extending members -18 and, in turn, firmly holding the pane 10 in the slot 16.*' To remove or replace the pane 10, the member 38 issimply slid longitudinally 1n the grooves 36; the clamp 22 'is then removed and .the panecan be inserted It is apparent that herein is provided a window frame which will hold a glass pane iirml will allow free 'expansion and' contraction of the glass, and which. will .elimi,

l is shown nate the tedious task of puttying and the consequential delay in waiting for the putty to set, and also eliminate the necessity of repainting vthe newly puttied edges.; In addition a neater frame is provided, one which is extremely strong and one fromwhich any warping tendencies are absent.

env,

vnation, a plurality of hollow casings successively joined at their ends to form a rectangle, each ofthe inner edges of the said casings` being provided with a slot into which a win.-

dow pane is-adapted to fit and means within' each casing for clamping the edges of the pane in the slots, said means comprising a plurality of substantially tubular longitudinally open resilient members, each casing being provided with a pluralityof transverse openings for the insertion or removal of the said resilient members.A

2. A window frame, including in combination, a plurality of hollow casings successively joined at their ends to form a rectangle, each of the inner edges of the said casings being provided .with a slot into which a window pane is'adapted to. lit and means within eachcasing for clamping the edges oi the pane in the slots, said means comprising two inwardly turned juxtaposed portions in-. tegral with the inner edges of the casing forming a lining for each slot, and means for.

which each pair of/inwardly turned members are adapted to be inserted, andmeans for inserting the window pane within the .frame r 3. A window frame, includingin combil l nation, a plurality of hollow casings successively joined at their ends to form a rectan le, each of the inner edges of the said casings e ing provided with a slot into which a window pane is adapted to fit and means within each casing for clamping the edges of the pane in the slots, said means comprising two inwardly turned juxtaposed vportions integral with the inner edges ofthe casing forming a lining for each slot, and means for intimately contacting each inwardly turned portion with each side of the edge of the pane', said means including a plurality of substantially tubular resilient members each having a longitudinal opening therein into which each pair of inwardly turned m'embers are adapted to be inserted, and -means for inserting thc window pane within the frame, said means, comprising a slidable top on the upper casing of the Vframe and means integral with the inner side of the slidable top for. compressing the said tubular ,resilient member.
